That would be CARD=Device to use the USB Device, and that actually works. --rate 44100 does not seem to work. Is it possible that the USB device is only able to play back at 48 kHz so that the PC needs to resample, or can this be a driver issue that the frequency is not correctly selected? And even after successful playback with --rate 48000 and the DAT deck still being synced to the input, iecset -c iec958:CARD=Device,DEV=0 says Rate: 44100. > You might also need to mess with AES0 settings. Google for that. Google results are inconclusive, a ton of forum entries like "AES0=number fixed it for me", but nothing resembling an explanation, and nothing in the Documentation subdirectory in the kernel tree.
